ContentIndex.delete()
Draft
This page is not complete.
The delete()
method of the
ContentIndex
interface unregisters an item from the currently indexed
content.
Calling delete()
only affects the index. It does not delete anything
from the Cache
.
Syntax
ContentIndex.delete(id).then(...);
Parameters
This method receives no parameters.
Return value
Returns a Promise
that resolves with undefined
Exceptions
No exceptions are thrown.
Examples
Below is an asynchronous function, that removes an item from the content index
. We receive a reference to the current
ServiceWorkerRegistration
, which allows us to access the
index
property and thus access the
delete
method.
async function unregisterContent(article) {
// reference registration
const registration = await navigator.serviceWorker.ready;
// feature detect Content Index
if (!registration.index)
return;
// unregister content from index
await registration.index.delete(article.id);
}
The delete
method can also be used within the
service worker
scope.
self.registration.index.delete('my-id');
